Mobile - broken scrolling in the "saved words" with tags filter

On a mobile phone: (android, firefox)

  1. Go to Language Reactor
  2. Select to show one tag from the list of tags
  3. Scroll couple of screens down
  4. Click on the word to see details
  5. Close the details - the page will auto-scroll to the top

Instead, the position of the scroll should be preserved, not reset.
